  - terrain condition - high obstruction(s) (contributing factor)
  - clearance - not identified, other crewmember (cause)

## Analysis

WHILE INSPECTING A TRANSMISSION WIRE TOWER, THE LEFT SKID BECAME ENTANGLED WITH THE POWER LINE GUIDE. THIS PULLED THE HELICOPTER OUT OF CG. WHILE THE PLT WAS TRYING TO CORRECT THE PROBLEM, THE M/R BLADE CONTACTED THE TOWER & STRUCK THE TAIL BOOM SEPARATING THE T/R. THE PLT STATED THAT THE OPERATION HAD BEEN PREVIOUSLY PERFORMED WITHOUT INCIDENT, & THAT THE CREWMEMBER WHO WAS INSPECTING THE POWER LINE GUIDE FAILED TO CHECK THE ACFT CLEARANCE PRIOR TO SIGNALING THE PLT TO CLEAR TO TOWER.
